В общем не работал у меня звук как только поставил Ubuntu 14.04. поставил алсамиксер, всё настроил как надо и так далее, всё заработало. потом заметил, что не работает микрофон, лазил, лазил, в итоге снёс pulseaudio и оставил алсу. ребутнул компьютер и вижу, что он во-первых намного дольше загружается, чем раньше, не видит мою звуковую карту и в параметрах системы есть только язык системы, принтеры, программы и обновления и служба landscape. lspci -v
